Q: What is a big end bearing in vehicle?

A: The big-end bearing of the connecting rod is connected with the crank pin to reduce the wear of the big-end bearing of the crank pin. The connecting rod big end bearing is a split sliding bearing. The large-end bearing of the cross-head connecting rod is often made separately, and then the connecting rod bolt is fixed to the shaft, and the antifriction alloy is often directly cast on the inner surface. For large-end bearings without cross-head connecting rods, the upper half is often integrated with the shaft, while the lower half bearing cover is manufactured separately, and then the connecting rod bolt is fixed to the upper half, and it is on the bearing. The inner surface of the lower half is equipped with bearing pads. In order to lubricate, oil holes are drilled in the big-end bearings, and oil grooves and garbage grooves are made on the surface of the anti-friction alloy.
